Polyurethane
- It’s branch of chemical substance which is the main materials of fundamental and the result of reaction between Polyol and Isocyanine.
- Polyurethane can be used in various types such as: foam Product – film- elastomer-powder- liquids – emulsion.
- Polyurethane in various shapes are useful in the world such as soft foam- hard foam –elastomer thermo Plastic – resin – color.
Polyurethane in shoe industries since improvement of leg – appropriate durability- low weight – good substructure resistance against water – Oil- chemical substance- flexibility- not to slip- appropriate surface tension, in shoes industry Polyurethane are used.
- Polyurethane are presented in 3 ways:
- Isocyanate
- Polyol
- Catalyst
